The denser liquid sinks to the bottom, but the lava lamp light heats it up until it expands and becomes less dense, causing it to rise upward. … Instead of using a light, in our homemade lava lamp, we used Alka-seltzer to power the lamp. The Alka-seltzer reacts with the water to produce carbon dioxide gas bubbles.
What happens in the lava lamp experiment?
The Alka Seltzer reacts with the water to make bubbles of carbon dioxide. The bubbles attach themselves to the blobs of colored water and bring them to the top of the glass. When the bubbles pop the blobs of colored water fall back to the bottom of the glass. This lava science experiment is sure to WOW your kids.
What liquid is inside a lava lamp?
The whirling globs we remember are made mainly of paraffin wax, with compounds like carbon tetrachloride added to increase its density. The liquid the wax floats in can be water or mineral oil, with dyes and sparkles added for whimsy.
What happens to the particles in a lava lamp?
The molecules move faster. The globs become less dense than the surrounding liquid. They rise and start to float around!
Why does the lava lamp experiment work?
How it Works: The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve.
How do you do the Skittles experiment?
Pour over enough cold water to cover all the Skittles and the plate itself on the first plate. Pour over enough warm water to cover all the Skittles and the plate itself on the second plate. Watch and wait as a rainbow appears on the second plate, the colors will move towards the middle and create a whirl of color.
Why does my lava lamp have bubbles?
Small bubbles in the lava are normal particularly when you first receive the lamp. As you use this over time the bubbles will reduce.
Is the stuff in lava lamps toxic?
The liquid inside lava lamps is non-toxic, so it will not poison children or pets.
Is it safe to drink a lava lamp?
Laboratory tests are done on leftover parts from AW’s lava lamp. Wax, kerosene, and polyethylene glycol are found, all dissolved in water. Wax is, in general, non-toxic in humans. Kerosene, at least in the amount that could be found in a lava lamp, is not poisonous, but the polyethylene glycol, could be a problem.
How do you change the water in a lava lamp?
Add a teaspoon of canning salt, pickling salt or Epsom salt to the water, and agitate it gently until the salt dissolves. Alternatively, you can make an Epsom salt solution outside the lamp, adding Epsom salt to cool distilled water until the salt will no longer dissolve in the water.
Do lava lamps make noise?

What are the ingredients in a lava lamp?
A lava lamp is made by mixing alcohol and water and mineral oil and dyes, combining each separately. By mixing water and alcohol in the correct proportions, the mineral oil can be made to float. The correct ratio is about six parts 90% isopropyl alcohol to 13 parts of 70% isopropyl alcohol.
